* implement correct Etag and If-None-Match handling, responding with
304 Not Modified if they match
* introduce SessionState and State string type aliases to ensure we are
using the correct fields for those, respectively
* extract the SessionState from the JMAP response bodies in the
groupware framework instead of having to do that in every single
groupware API
* use uint instead of int in some places to clarify that the values are
>= 0
* trace-log how long a Session was held in cache before being evicted
* add Trace-Id header handling: add to response when specified in
request, and implement a custom request logger to include it as a
field
* implement a more compact trace-logging of all the methods and URIs
that are served, to put them into a single log entry instead of
creating one log entry for every URI
* add a GET /accounts/{a}/boostrap URI that delivers the same as GET /
but also mailboxes for a given account, in case the UI remembers the
last used account identifier, to avoid an additional roundtrip
* streamline the use of simpleError()
* add logging of errors at the calling site
* add logging of evictions of Sessions from the cache
* change default Session cache TTL to 5min instead of 30sec
* add more documentation for properties
* fixes after a bit of trial-and-error with go-swagger
* fix email filter marshalling when there are no search criteria
* introduce an apidoc.yml that contains Swagger data and is merged when
generating the swagger.yml from sources
* ensure that all the jmap responses contain the SessionState
* implement missing errors that were marked as TODO
* moved common functions from pkg/jmap and pkg/services/groupware to
pkg/log and pkg/structs to commonalize them across both source trees
* implement error handling for SetError occurences
* Email: replace anonymous map[string]bool for mailbox rights with a
MailboxRights struct, as the keys are well-defined, which allows for
properly documenting them
* introduce ObjectType as an "enum"
* fix JSON marshalling and unmarshalling of EmailBodyStructure
* move the swagger documentation structs from groupware_api.go to
groupware_docs.go
* fix: change verb for /groupware/accounts/*/vacation from POST to PUT
* refactor the jmap package to split it into several files as the
jmap.api.go file was becoming too unwieldy
* refactor the Groupware handler function response to be a Response
object, to be more future-proof and avoid adding more and more
return parameters while handling "no content" response as well
* more godoc for the JMAP model
* add Email creation, updating, deleting (Email/set,
EmailSubmission/set)
* add endpoints
- POST /accounts/{accountid}/messages
- PATCH|PUT /accounts/{accountid}/messages/{messageid}
- DELETE /accounts/{accountid}/messages/{messageid}
